Hi,
I ported my app to GWT 1.6.4 and the Google Eclipse Plugin and it
worked on my Linux desktop. But when I checked out the project on my
Windows notebook and tried to run it in hosted mode, I started to
receive exceptions. See below for the first exception, which is a
ClassCastException in JsValueGlue. In the application it is thrown
inside Image(String filename).
This exception seems to be catched somewhere and the application
continues, but a similar exception seems to get thrown on each mouse
event in the event loop, so the application can't be used.
I need help, because I'm stuck with this problem. I already asked once
in this group but got no answer. As the application runs fine on Linux
(checked out from the same repository), I figure it might be a GWT bug
with Windows or Internet Explorer? I could provide further details
from the debugger, it you tell me what you need. Unfortunately the
application is rather complex and I can't provide a simple sample
showing the problem.
Thanks in advance for any help!
Best wishes
Michael
